I believe it's a bit strong with the amount of regen they have running around and some fairly tanky champs. A 12 damage champ hits guardian of eretat for 7 damage with tough 2, with tough 2 and the bonus from relic guardian it's at 5 total damage. I believe sl needs a few champs to get looked at. I'm fine with the bonus, but when I see the bonus + tough and then regen or the bonus + dragon flight and like evasive, void shield, scale armor it bothers me. If were going to leave champs like this at least give them a common drawback like vindrax has vulnerable:magical. Good example a 20 damage ranged champ attacking sonic bolt 18 with def 16 with bonus 14 with dragonflight 7 with evasive 3....... Let that sink in and then note this champ has 11 damage and 55 health, so engaging it in melee is no joke and hitting it from range is laughable not to mention it will most likely teleport next to you ranged units.
